“You know, I’m working on a television show now, so I’m juggling working and being a mom and breast feeding while I’m working,” she tells PEOPLE at the Fame & Philanthropy Post Oscar party in Beverly Hills on Sunday.

Already mom to 5-year-old Nahla, Berry says, “It’s a whole new life for me now all over again, having a new little baby again.”

The actress, 47, who is working on the TV series Extant, says she’s still trying to get her pre-baby figure back, so she chose a dress that works with her current curves.

“This is vintage Versace,” she says. “It’s one of Gianni’s last pieces. I never go wrong with Versace. I love Versace. And you know, I’m not quite where I want to be with my body, so this was a great dress for me to wear tonight!”

The Oscar winner says she is “working hard” to lose the baby weight, but despite all the effort and changes, motherhood is “fantastic.”

And the baby is “more fantastic,” she says.

Berry adds that she doesn’t see any more children in her future.

“I’m surprised I had the one I just had! So I doubt God is going to bless me again. I think I’m done!”
